# BETA.DIST

Returns the beta distribution. The beta distribution is commonly used to study variation in the percentage of something across samples, such as the fraction of the day people spend watching television.

## Syntax

BETA.DIST(x,alpha,beta,cumulative,[A],[B])


### Parameters

Term Definition
x The value between A and B at which to evaluate the function
Alpha A parameter of the distribution.
Beta A parameter of the distribution.
A Optional. A lower bound to the interval of x.
B Optional. An upper bound to the interval of x.

## Return value

Returns the beta distribution.

## Remarks

• If any argument is nonnumeric, BETA.DIST returns the #VALUE! error value.

• If any argument is not an integer, it is rounded.

• If alpha ≤ 0 or beta ≤ 0, BETA.DIST returns the #NUM! error value.

• If x < A, x > B, or A = B, BETA.DIST returns the #NUM! error value.

• If you omit values for A and B, BETA.DIST uses the standard cumulative beta distribution, so that A = 0 and B = 1.

• This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.
